Description
We have suspicion that there’s a connection between corrupted databases and calling “restore all” during runtime.
And that’s also the reason why we have global reset freeze/crash mentioned in PAS-12.
The steps to reproduce are simple.
1) call PAS tool restore function:
persadmin_tool restore FactoryDefault 0 "" -1 -1
Normally you should see return error code = 0 which means SUCCESS.
2) After few attempts (sometimes it can happen after first call, sometimes after 10th)
3) If you will notice that procedure has been frozen before reaching any return error code – you can be sure that one of cached.itz db files is corrupted. And restore feature doesn’t work even after system restart.
So the first conclusion is that there’s something wrong with calling restore when applications use PCL.
I have also checked the structure of those corrupted databases. After “restore all” crash/freeze I have completed existing database files and checked those with my tool.
Below you see the details. I’m sorry for that bad looking output, but I hope it will be readable enough.
Please pay close attention to those strange looking block offsets and delimiters.
